Blowup and blowup time for a class of semilinear pseudo-parabolic equations with high initial energy

摘要

We establish a new finite time blowup theorem for the solution to the initial boundary value problem of a class of semilinear pseudo-parabolic equations at high initial energy level. And we also estimate the upper bound of the blowup time. (C) 2018 Elsevier Ltd. All rights reserved.
